Fig. 28 shows in top-plan-view a device for adjusting the liquid-containers and for securing the same in the adjusted position.

In theapparatus shown in Figs. 1 to 3 the liquid-containers 1 and 2, placed for instance on a heating body H, and the porous-body 3 are connected with one another by rods 4 and 5 traversing lugs 6 at the ends of the liquidcontainers 1 and 2 and lugs 7 at the ends of the porous-body 3 so that the two li uid-containers can be adjusted, the one wit 1 regard to the other. The rods 4, 5 have threaded ends 4, 5 on which nuts-4", 5" are screwed. By means of these rods the distance at which the liquid containers 1, 2 are spaced can be increased or decreased.

In the form of construction shown in Figs. 4 to 6 the liquid-containers 1 and 2 are hingedly connected with the porous body. The perous body is composed of two elements 3 and 3 connected the one with the other by a pivot- 90 bolt 8 and hingedly connected to the corresponding liquid-container 1 or 2 by' a bolt 9 or 10 respectively. Extensions 3 and 3 respectively of the two elements 3 and 3" of the porous body'project into the liquid-containers I and 2. The adjusting of the two liquidcontainers is effected by means of rods 11 and l2'having each a handle 11, 12 respectively at the middle and right hand thread on the one half and left hand thread on the other 9 showing the provision of perforations 55 half, said threaded portions being screwed through internally threaded lugs 13, 14 respectively of the liquid-containers'l and 2 so that, by rotating the rods 11 and 12 in the one or other direction, the liquid-containers 1, 2 are moved the one towards the other or the one away fromthe other.

The liquid-containers 1 and 2 as shown in Figs. 7 to 9 are hingedly connected with the porous body composed of two elements. The elements 3 and 3 of the porous body, connected the one with the other by a pivot-bolt 8, form a roof, the side walls of which form steps 3. t The object of this arrangement will be hereinafter explained. The elements 3, 3 of the porous body are connected with the liquid-containers 1 and 2 by rods 9 and 10. From the bead-shaped lower end of the elements 3, 3 strips of fabric 3*, 3 hang down which dip into the liquid in the containers 1 and 2. Tubular sockets 15, 15 extending from the corresponding end of the liquid-containers 1, 2 are connected the one with the other by a flexible tube 15. To one of the tubular sockets, for instance the socket 15*, a tubular socket 16, extending to a vessel 16, is connected said vessel containing a float 16 which carries a valve-pin 16, the valve-seat 16 for said valve-pin being arranged in a. tubular socket 16 upwardly extending from the lid 16 of the vessel 16. The tubular socket 16 is connected by a tube 16 to a reservoir, not shown. from which, when valve 16 is opened, liquidflows into the vessel 16 and thence into the containers 1, 2 until the liquid in the casing and the containers has risen to the level at which the float closes the valve interrupting thus the liquid-admission. The level of the liquid in the containers 1 and 2 is constantly maintained at the same height. The containers 1 and 2 are connected the one with the other by means of rods 11, 12, having handles 11, 12 on the middle and right hand threads on the one half and left hand threads on the other half screwed into lugs 13, 14 being internally threaded accordingly and which extend from the containers 1 and 2. The lugs 13, 14 are rotatably arranged in the walls of the containers and adapted to be securedin position by means of thumb-nuts 13", 14 screwed on the shaft 13, 14*.of the lugs 13 and 14. As shown in Figs. 10 to 12 the liquid-containers 1 and 2 are hingedly connected to a wire-frame consisting of two equal or unequal halves 17 and 17 connected the one with the other by means of a rod 8, rods 9, 9 serving for hingedly connecting the containers with the wire-frame. The side-part of each of the two halves 17, 17" of the wireframe is connected with the other half by means of rods 9", 9 arranged between the rods 8 and 9. This wire-frame serves to hold a porous-sheet 3 of woven or knitted fabric, blotting paper or the like, the two ends of which hang into the containers 1 and 2. The two containers are connected the one with the other by a rod 11 having a handle 11 at the middle, left hand threads on the one half and right hand threads on the other half. The rod is screwed through internally threaded lugs 13 upwardly projecting fromthe liquid-containers 1, 2 respectively.

According to Figs. 14 and 15 the two frame elements 17, 17?, hingedly connected the one with the other and with the corresponding liquid-contained 1 or 2, form together with the porous body 3 of fabric, blotting paper or the like a saddle roof. The connection of the liquid containers 1, 2 consists of rods 18 and tubes 18, the rods being telescoped into the tubes and adapted to be secured in posi- 'tion by means of screws 18".

In the form of construction shown in Fig.

13 a frame 17 is used which permits of pro-' viding steps in each half of the porous body 3 or to let sag the halves of the porous body at certain points as shown;

The liquid-containers 1 and 2 are connected the one with the. other by a rod 40 pulled against the end-walls of the containers by means of a hook-shaped screw-bolt 41.

The frame 17, 17 in the form of construction shown in Figs. 16 to 17 is made of wire and designed to support a separate vessel 20 for an antiseptic, pharmaceutic or cosmetic liquid in which a porous body 21 is arran ed, the ends of which rest on the porous bo y 3 to transmit to the same liquid from the vessel 20. A rod 22 downwardly extending from the bottom-plate of the vessel 20 is adjust-ably mounted in sleeves 23 and 24, which are hingedly connected to the wireframe 17, 17 and adapted to be adjusted in vertical direction and to be secured by means of a set-screw 25 in any adjusted position.

The containers 1 and 2 in the form of construction shown in Figs. 18 to 21 may be adjusted in vertical direction, the halves of the frame 17, 17 and the porous body 3 being adapted to be inclined either in upward direction, as shown in Fig. 18, or in u ward and downward direction, as shown in ig. 19, at different angles.

They might both be situated in a horiipntal plane 20) or sag as shown in The porous body 3, which may be of clay or the like (Figs. 1 to 9) or of fabric (Figs. 10 to 23), can have perforations 26, as shown in the top-plan-view 22, or perforations 26 and slots 26, as shown'in Fig. 23.

The device illustrated in Fig. 18 is arranged above the plate P of a. heating body H. The liquid-container 1 rests on a support 39 and has a. guide-plate 38 designed to conduct the air to underneath the device for moistening and purifying the air.

One of the screw-bolts 48, having a hookthe liquid containers 1, 2 and the porous shaped outer end 41 and designed for clamping the rods .40 on the end-walls of the liquidcontainers 1 and 2, is shown in Fig. 24 of the drawing. The screw-bolts 41 are inserted through holes in the end-walls of the containers 1 and 2 and secured by means of nuts 41*. When the nuts 41 are tightened, the rods 40 are pulled by the hooks 41 against the outer surface of the end-walls of the containers. j j

A modified device for connecting the liquid containers 1 and 2, shown in Figs. 25 to 27 consists of two lugs 27, 27 and 28,- 28* respectively suitably spaced the one from the other and fixed on the end-walls of the containers 1 and 2, a nut 29, 30 respectively being clamped between the two corresponding lugs 27 or 28 so that it can neither shift nor rotate, one of said nuts 29, and 30 having right hand threads and the other left hand threads. A rod 42, having a handle 42 at the middle, is inserted through the lugs 28, 28 and nut 30 and through the lugs 27, 27 and nut 29, the portions of said rod threaded through the nuts having correspondingly directed threads.

The adjusting device shown in Fig. 28 consists of a bar 43 adapted to be secured in lugs 14 of the liquid-containers 1*, 2 by means of set-screws 14.

The liquid-containers 1 and 2 maybe made of any convenient material, as clay, porcelain, metal or' enamelled sheet-metal. The vessel 20 or several such vessels, containing the antiseptic, pharmaceutic or cosmetic preparation, may be arranged at any other point of the apparatus than shown, for instance between body By the step 3", 3 in the porous body (Figs. 7 to 9 and 13) a so called retum-head is produced for the liquid elevated by the porous body from the containers 1 and 2. On the first step 3, or 3 a certain quantity of liquid accumulates owing to the return-head formed by this step this liquid-quantity rising in the porous body up to the next higher step on which it accumulates again to rise up to the highest point of the porous body.

By this apparatus, the construction of which might be still further modified, is obtained that the air-currents in proximity of heating bodies are intercepted and conducted in such a manner that the air must flow along wet and roughsurfaces and eventually trav-,

erse the same, in order to obtain a hygienic and aesthetic improvement of the air.

The apparatus serves: 1.--To moisten dry air up to a certain degree,

2.To efiect purification of the air in acting as a strip or passage-filter,

3.'To absorb gases of the dust-cokefying on the heating body,

4.To produce and admix with the air ous body dipping'into the liquid of said containers and extending above and between said containers, and means for adjusting said liquid-containers with regard to each other and to said porous body. 4
